Two field strains of the Indianmeal moth, Plodia interpunctella (Hübner); red flour beetle, Tribolium castaneum (Herbst); and lesser grain borer, Rhyzopertha dominica (F.), and one field strain of the rusty grain beetle, Cryptolestes ferrugineus (Stephens), were collected from hard red winter wheat stored on farms in northeastern Kansas. Fifty eggs of P. interpunctella and 25 beetle adults of e...

Phosphine resistance in stored-product insects occurs worldwide and is a major challenge to continued effective use of this fumigant. We determined resistance frequencies and levels of resistance in Tribolium castaneum and Plodia interpunctella collected from California almond storage and processing facilities. Discriminating doses of phosphine were established for eggs and larvae of P. interpu...

Dried apricot is one of the stored fruit most endangered to be infested by the Indianmeal moth, Plodia interpunctella (Hübner). The aim of the present study was to identify volatile compounds from dried apricot that elicit an electrophysiological response in P. interpunctella adults. The volatiles were collected from the headspace of a glass vial with dried apricots using closed-loop-stripping ...

This study investigated the acaricidal and insecticidal effect of local lupin (Lupinus albus L. Fabaceae) seed extract against Tetranychus urticae Koch (Acari: Tetranychidae), Callosobruchus maculatus F. (Coleoptera: Chrysomelidae), Plodia interpunctella (Hubner) (Lepidoptera: Pyralidae) metabolite content seeds. In tests for T. leaf-disk bioassay was employed. Contrarily, two μL were topically...

This study was conducted to determine the insecticidal activity of essential oils from oregano, Origanum onites L. (Lamiales: Lamiaceae), savory, Satureja thymbra L. (Lamiales: Lamiaceae), and myrtle, Myrtus communis L. (Rosales: Myrtaceae) against three stored-product insects. Essential oils from three species of plants were obtained by Clevenger-type water distillation. The major compounds in...

The Indianmeal moth, Plodia interpunctella (Hübner), was selected as a representative stored-product moth to test the validity of contour mapping of trap catch for pest monitoring in warehouses and retail stores. Three experiments, each replicated five times, were conducted in a 3.2 by 9.0-m aluminum shed. Each experiment involved placing pupae at a single release point (source) and recording t...
